Title: Apparatus for automatically turning pages
IPC: B42D9/06
Filed: 1920-10-26
Abstract: 153,022. Al Bustany, S. Sept. 5, 1919, [Convention date]. Leaf-turners.-In a leaf-turner for books &c., the page is lifted by a suction device connected to a vacuum pump and the movement of the page is completed by a bent rod which moves more rapidly than, and passes under, the suction device, the rod in its movement opening a valve to release the suction device from the page. The suction device a which is adjustably mounted on a tube a<2> is connected to a pump b by a flexible tube a<1>, the tube a<2>, a joint a<3>, tube a<4>, flexible tube a<5>, and the valve tube a'. The joint a<3> is mounted on a shaft c carrying a pinion c<1> gearing with a spring-controlled sliding rack c<2> having at one end a stop c<5> which is engaged by the end of a spring-controlled pivoted lever d connected by a cable d<3> to a pedal. By means of a spring rod a<7>, the lever d also operates the valve a<6>. On the shaft c is also mounted a grooved sector f to which is connected a cord f<2> passing round, and secured to a pulley f<1>. Mounted on the shaft f<3> of the pulley f<1> is a bent spring-controlled telescopic rod f<4>. The air-inlet valve, on the tube a<4>, Fig. 3, is constituted by a flat spring g' carrying a plug g of elastic material placed opposite a hole in the tube a<4>. The spring g<1> is actuated by a cam h on the end of the tube a<4>, the motion of the cam being limited by two stops h<2>, h<3>. In the operation of the device, the suction device a is adjusted and placed on the bottom right-hand corner of the page. When the pedal is depressed, the movement of the lever d first opens the valve a<6> causing the device a to adhere to the page and then moves the rack c<2>. The rotation of the shaft c lifts the suction device a and moves the rod f<4> under the page. The lever h<1>then comes into contact with the stop h<2> and opens the valve g which releases the device a from the page and the rod f' having a more rapid movement than the device c causes the page to pass under the latter and lays it down on the left-hand side of the book. When the pedal is released, the springs return the device a and rod f<4> to their original positions and the lever h<1> contacting with the stop h<3> closes the valve g. The frame e may also serve as a music rest or reading desk.

Title: 7-aminocephalosporanic acid and derivatives thereof
IPC: A61K31/545
Filed: 1975-07-21
Abstract: Compounds of the formula: <IMAGE> in which X is hydrogen, azido or -YR1, Y is oxygen or sulphur and R1 is lower alkyl, acyl or a heterocyclic radical, and Z' is hydrogen or an ester radical, are prepared from corresponding compounds of the formula: <IMAGE> in which R is acyl and Z is hydrogen or the residue of a mixed anhydride or of an ester. To do this, the starting material is reacted with an agent which forms imino halide in the presence of an amine under anhydrous conditions, and the reaction product is reacted with an anhydrous alkanol; the resulting 1-deoxy-7-imino ether compound is then subjected to acid hydrolysis. The hydrolysis simultaneously unblocks the 4-carboxyl group when Z is a mixed anhydride or a readily hydrolysable ester. The compounds are intermediates for the preparation of antibiotics of the cephalosporin series.

Abstract: 1,068,961. Riveting. TEXTRON INDUSTRIES Inc. Aug. 4, 1964 [July 31. 1963], No. 30987/64. Heading B3U. A pulling head for setting tubular rivets by break-off mandrels comprises a sleeve connected to the body of a power tool and having a nose for bearing on the rivet head, a tubular draw-bolt reciprocable away from the nose for pulling the mandrel and movable toward the nose to a mandrel receiving position, the nose and the adjacent end of the draw-bolt having axially aligned apertures, mandrel gripping jaws in the draw-bolt, means in the draw-bolt to close the jaws when the drawbolt is pulled relatively to the sleeve, means to urge the jaws to the gripping position and means to limit the closing of the jaws in the mandrel receiving position. The sleeve 8 is supported by a liner 13 screwed into a power tool 9 and has a nose 16 which bears on the head 2 of the rivet 1. A spring 18 biases the sleeve to the right as seen in Fig. 5. A pin 21 enters a slot 22 which guides the pin but does not limit its stroke. The draw-bolt comprises a base section 28 which screws into the piston shaft 31 of the power tool and a jaw holder 32 which screws into the base 28 and has a conical surface 41 which coacts with the jaws to close them to the gripping position. The jaws 37 are formed on the limbs of a spring collet 26 which has a conical forward end to coact with the surface 41. The means to urge the jaws to the gripping position comprises a block 44 which extends through elongated slots 46 in the jaw holder and into an enlarged bore 47 of the liner 13. A spring 52 and plunger 51 hold the block 44 against a shoulder 48. An ejector tube 53 which extends through the device and through the piston-rod of the power tool, has a threaded flange 54 which screws into the piston shaft 31. A non-return pin 57 extends across the mandrel receiving aperture in the nose 16 and is resiliently held by a spring ring 59. Operation.-A mandrel 6 is inserted into the jaws 37 and as the draw-bolt 23 moves away from the nose 16 the block 44 holds the jaws stationary so that the surface 41 closes the jaws on to the mandrel. Further movement sets the rivet and the draw-bolt then begins to return to the initial position but the broken-off part of the mandrel 6 abuts the pin 57 and pushes the nose 16 and sleeve 8 away from the liner 13 thus compressing the spring 18. As the draw-bolt moves further to the left in Fig. 5, the block 44 abuts the shoulder 48 and the spring 52 is compressed and thus relieves the pressure on the collet 26. The pressure of the spring 18 acting through the broken mandrel 6 then moves the collet 26 away from the surface so that the jaws release the mandrel which is then propelled along the the ejection tube.

Abstract: 756,823. Batteries. SOC. E.R.E.C. SOC. D'ETUDES DE REALISATION ET D'EXPLOITATIONS COMMERCIALES: Oct. 27, 1954 [Oct. 28, 1953], No. 31008/54. Class 53. Apparatus for filling a number of cells with electrolyte comprises two relatively movable plates 3, 4 provided with openings 6, 7 which are normally out of register, the plate 3 forming the base of a reservoir 1 containing electrolyte, the cells being placed beneath the openings in the lower plate. As shown in plan in Fig. 2 the plates are provided with two series of openings and the plate 4 can be rotated relatively to the plate 3 which is fixed. A second fixed plate 5 having openings 9 may be provided below the plate 4. To make the openings watertight when out of register the openings 6 are closed by frangible diaphragms 8 which are supported by the solid parts of the plate 4. When the plate 4 is rotated to bring the openings 7 beneath the openings 6 the weight of the electrolyte breaks the diaphragms and electrolyte flows from the reservoir 1 into the cells. The plate 4 can be rotated by the devices shown in Figs. 3 and 7 and is returned to its initial position after the cells have been filled by a spring 10. In the arrangement shown in Fig. 3 the plate 3 is provided with an oblique passage 11 normally closed by a cap 15 which has a weakened part 16 enabling it to be readily broken whereupon liquid flowing down the passage 11 strikes the surface 13 of an opening 12 in the lower plate and rotates it to open the passages 6, 7. A member 18 wedged between the plates 4, 5 keeps the opening 12 in communication with the cell below it when the openings 6, 7 are closed so that electrolyte can flow down the passage 11 as soon as the cap 15 is removed. The member 18 drops into the cell below and when the plate 4 is returned to its initial position by the spring 10 it is rotated sufficiently to close the openings 12, 14. Fig. 7 shows an alternative method of moving the plate 4 in which a closed recess 24 partly overlaps an opening 21 closed by diaphragms 22, 23 in the upper plate. When a spring-controlled plunger 26 is depressed it breaks the diaphragms and its lower face 20 engages a bevelled edge 25 on the wall of the recess 24 and moves the plate 4 as it passes downwardly into the recess 24. In another modification the plate 4 is moved by a screw and nut arrangement.
